The electrocatalytic splitting of water is recognized to be the most sustainable and clean technology for the production of hydrogen (H ). Unfortunately, the efficiency is seriously restricted by the sluggish kinetics of the oxygen evolution reaction (OER) at the anode. In contrast to the OER, the electrooxidation of organic compounds (EOO) is more thermodynamically and kinetically favorable. Thus, the coupling of the EOO and hydrogen evolution reaction (HER) has emerged as an alternative route, as it can greatly improve the catalytic efficiency for the production of H . Simultaneously, value-added organic compounds can be generated on the anode through electrooxidation upgrading. In this Minireview, we highlight the latest progress and milestones in coupling the EOO with the HER. Emphasis is focused on the design of the anode catalyst, understanding the reaction mechanism, and the construction of the electrolyzer. Moreover, challenges and prospects are offered relating to the future development of this emerging technology.
水的电催化分解被认为是生产氢气（H₂）最可持续且清洁的技术。不幸的是，效率受到阳极析氧反应（OER）缓慢动力学的严重限制。与OER相比，有机化合物的电氧化（EOO）在热力学和动力学上更有利。因此，EOO与析氢反应（HER）的耦合已成为一种替代途径，因为它可以大大提高H₂生产的催化效率。同时，可以通过电氧化升级在阳极生成增值有机化合物。在这篇微型综述中，我们重点介绍了EOO与HER耦合的最新进展和里程碑。重点集中在阳极催化剂的设计、反应机理的理解以及电解槽的构建。此外，还针对这项新兴技术的未来发展提出了挑战和前景。
